Croagh Patrick (Irish: Cruach Phádraig, meaning '(Saint) Patrick's stack'), nicknamed 'the Reek', is a mountain with a height of 764 m (2,507 ft) and an important site of pilgrimage in County Mayo, Ireland. The mountain has a pyramid-shaped peak and overlooks Clew Bay, rising above the village of Murrisk, several kilometres from Westport. It has long been seen as a holy mountain. It was the focus of a prehistoric ritual landscape, and later became associated with Saint Patrick, who is said to have spent forty days fasting on the summit. There has been a church on the summit since the 5th century; the current church dates to the early 20th century. Croagh Patrick is climbed by thousands of pilgrims every year on Reek Sunday, the last Sunday in July, a custom which goes back to at least the Middle Ages. Croagh Patrick is the fourth-highest mountain in the province of Connacht on the P600 listing after Mweelrea, Nephin and Barrclashcame. It is part of a longer east–west ridge; the lower westernmost peak is named Ben Goram.
